|
98 Beremiz reference runtime implementation supports PYRO and WAMP protocols. |
|
99 This example shows how to use Web Application Messaging Protocol (WAMP). |
|
100 |
|
101 WAMP can be used to build distributed systems out of application components which are loosely coupled and communicate in real-time. No direct connection between IDE and PLC are necessary. |
|
102 |
|
103 WAMP is in a process to be published as official IETF standard. Draft specification is already available on IETF website. |
|
104 |
|
105 To use this example you need WAMP router and standalone running Beremiz_service. |
|
106 1. See README file in project's directory with detailed instructions for |
|
107 setup Crossbar.io, router for open Web Application Messaging Protocol (WAMP). |
|
108 2. Run crossbar |
|
109 3. Create service working directory and copy wampconf.json from project_files to created directory |
|
110 4. Run Beremiz_service: |
|
111 ./Beremiz_service.py -x 0 <working directory> |
